FILTER.

Specification of Letters Patent, Patented J a 18 1921 Application filed April 23, 1920. Serial No. 376,035.

vented a new and useful Filter, of which the following is a specification.

This invention relates to a filter partlcularly. designed for use in separating the lighter and heavier portions of mineral 011s and more especially for removing oil from the heavy preci itates or basic settlings better known as 5 S. which accumulate on the bottoms of tanks where oil is stored.

A further object is to provide a filterof this character which is simple, durable and efficient and will operate continuously, it being possible to installthe filter in tanks of different sizes.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanylng drawing, which is a section through a filter embodying the present improvement, the preferred form of the invention has been shown.

Referring to the drawing by characters of reference, 1 designates a tank of any desired proportions provided upon the bottom thereof with a central supporting frame 2 from which extends an upwardly projecting pipe ,3 opening through the top 4 of the tank. The mineral oil is adapted to be sup lied to this pipe 3 through a feed pipe 5. adiating from the structure 2 and withinthe tank are upwardly diverging beams 6 supporting a conical container 7 preferably formed of sheet metal andthelowermost portion of which is preferably filled with concrete as shown at 8 so as to hold the parts properly spaced and anchored relative to each other.. The container 7 is spaced from the wall of the tank as indicated at 9 and supported above the container are transverse beams 10' on which is erected a foraminous partition 11. Filtering material such asexcelsior and with a foraminous top 13.

Outlet pipes 14 are extended from the bottom portion of the container 7 and through the wall of the tank and have valves 15. Additional outlet pipes 16 are extended through the wall of the tank 1 at points just below the upper edge of the container 7 and are also provided with valves 17. Another outlet plpe 18'is extended from the upper portion of the tank for the purpose of carrying off the refined or filtered oil.

In using theaapparatus the mineral oil is supplied to the tank through the pipe 3 and spreads out in the bottomportion of the tank. The lower portion of the tankl contains water which extends to the level of the pipes 16 and surrounds the'conical container 7. The mineral oil when discharged into the lower portion of the tank 1 will rise through the water and will overflow into the container 7which constitutes a settling compartment. Here the basic settlings will be separated from the remainder of the oil which remainder will arise through the foraminous partition 11 and the filtering material 12 andwill flow outwardly by way of the pipe 18. The basic settlings can be withdrawn through the pipes 14 by opening the valves 15 and the water can be drawn off whenever desired by opening the valves 17 and the pipes 16.

What is claimed is:

A filter including a tank, a supply pipe extendi pgodownwardly thereinto', a conical ingspaced at its margin from the wall of A the tank and having itssmall end lowermost and closed at its center about the pipe, means for drawing off the contents of the container,

means below the upper edgelof the container for maintaining water in the lower portion of the tank. at a predetermined level, a filtering material supported above the container, and means for drawing off the filtered liquid at a point above the, filtering material. i

Intestimony that we claim the foregoing as our own, we have hereto affixed our signatures in the presence of two witnesses.
